The only places where CheckedHandle is appropiate is with arguments to
runtime functions and values from Dart API functions.
For other places in the VM either normal Handle and ^=, or Cast is sufficient.
T::Cast is used when the value is guaranteed to be of type T (and never Object::null()).
Otherwise, the operator^= is used for casting.
Also fix a style issue where a Raw* should be used as return type.

This CL adds AND, OR, XOR and == operations on unboxed 64-bit integers
(aka. mints).
Unboxed mints are stored in xmm registers. Each xmm register location
has an additional bit to keep track of its value representation.
Unboxed mints are materialized on the heap on deoptmization in the same way as
unboxed doubles.
The SSE instructions used are available on all CPUs that support SSE 4.1.

Extend x64 disassembler with ability to decode and output recorded comments.
Example output (currently comments are emitted only by flow graph compiler at block/instruction boundaries, once instruction printing is refactored and supports printing into buffer simple "instruction" comment will be replaced with the actual IL construct):
;; B0
;; B1
;; instruction
0x007f0fff812525 00000055 49 bb 21 00 b4 04 10 mov $0x7f1004b40021,%r11

Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.

The purpose of this change is twofold:
1. Source in the bin directory can now use the same assertions as
source in the vm directory. The ASSERT macro used by the code
in runtime/bin was just defined to use assert from the standard
C library.
2. Moving other implementation parts from runtime/vm to
runtime/platform (e.g. classes Monitor and Mutex) for sharing
between runtime/bin and runtime/vm will be easier as these
implementations rely on these assertion macros.
Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.
All the code for asserts is still in the dart namespace.
Also re-arranged the order of includes to be alphabetically in
the files touched.

Print out first 5 elements of an array object, rather than
just 'Array'. This helps in particular in disassembled
method and stub calls which now print the content of the
IC cache and ArgumentsDescriptor arrays. E.g.:
0x7404a5 ff7508 push [ebp+0x8]
0x7404a8 ff750c push [ebp+0xc]
0x7404ab b9012f7000 mov ecx,0x702f01 Array[bitAndFromInteger, 1, null, null]
0x7404b0 bafd050003 mov edx,0x30005fd Array[2, 2, null]
0x7404b5 e8b6fcffff call 0x740170 [stub: InlineCache]
0x7404ba 83c408 add esp,0x8
